摘　　要：北天山前缘推覆断褶带构造非常复杂,目前还是地震勘探的空白区,但油气勘探前景非常有利,应用大地电磁测深(MT)法进行勘探,采用多种手段建立测区的电性层层序关系,根据采集的MT资料结合工区已有的重力、磁法、地震及钻井资料,对工区进行了综合地质解释,基本搞清楚了区内基底埋深、地层起伏、断裂展布规律及构造格架,为选区、评价、布署地震勘探提供了基础资料。As the complex structures of foreland fold-thrust nappe belt in Northern Tianshan, there is little seismic prospecting. However,based on the geological data, oil prospect of the area is good. During the magnetotelluric survey（MT）, the electric sequences were built with various means and the data interpretation was combined with the gravity, magnetic, seismic data and wells. Now the basement depth, strata undulation, fractures＇ distribution and tectonic frame are clear. These results are the basis for further evaluate oil ＆ gas prospect and layout seismic lines on the area in future.
